Abstract

The invention provides a receiver and a receiving method, which can achieve a monolithic integration of a plurality of receiving channels. The receiver comprises a zero intermediate frequency channel which conducts an IQ down conversion on the radio-frequency signal of a first frequency channel by means of a frequency division signal or a frequency doubling signal of a first oscillation frequency, and a superhet channel which conducts a down conversion on the radio-frequency signal of a second frequency channel by means of the frequency division signal or the frequency doubling signal of the first oscillation frequency, wherein the first frequency channel is different from the second frequency channel. The zero intermediate frequency channel and the superhet channel use the same oscillation signal or the frequency division signal or the frequency doubling signal of the oscillation signal, and thereby the problem that the oscillation signals influence each other due to the simple integration of two channels is overcome, and the monolithic integration of a plurality of receiving channels can be realized.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and more specifically, relate to a receiver and a receiving method thereof. Background technique [0002] At present, base stations or microwave transmission or terminal RFIC (Radio Frequency Integrated Circuit, radio frequency integrated circuit) receivers basically only receive single-band reception at the same time, and the future evolution requirement is ultra-wideband multi-band simultaneous reception. There is currently no good solution for multi-band simultaneous reception, and the most direct basic architecture is realized through simple parallel connection of two or more single-band receivers. [0003] If channels in multiple frequency bands all adopt a superheterodyne digital intermediate frequency (DIF, Digital Intermediate Frequency) architecture, the cost, area, and power consumption of the receiver are several times that of a single frequency band. For 3G (3 rd Gen...
